There is something similar in Matthew, chapter 24:1. Mark said that Jesus was leaving the Temple (Καὶ ἐκπορευομένου αὐτοῦ ἐκ τοῦ ἱεροῦ). Then one of his disciples (λέγει αὐτῷ εἷς τῶν μαθητῶν αὐτοῦ) pointed out to him the beautiful Temple buildings. This unnamed disciple called him teacher (Διδάσκαλε). He wanted Jesus to see and look at the wonderful or great stones and buildings (ἴδε ποταποὶ λίθοι καὶ ποταπαὶ οἰκοδομαί). The Jerusalem Temple had been under reconstruction since the time of Herod the Great in 19 BCE but would not have been completed at the time of Jesus, since it was only finished in 63 CE. However, most of the work would have been done by the time of Jesus.
